A B S T R A C T The detergent action and antiredeposition properties of a drycleaning solvent containing an anionic detergent, especially a petroleum sulfonate, are improved by the addition of a small amount of a polyglycol having an average molecular weight of 10,000 to 100,000, pre- ferably 12,000-60,000, and prepared from ethylene and propylene oxides. The invention is especially adapted to lower aliphatic hydrocarbons, such as carbon tetra- chloride, perchloroethylene and trichloroethylene.
